Holding up as a champ! 2 years agoalacran77127353
I bought this cap to replace a mishimoto cap that was torn-open by coolant pressure and heat. I normally drive in semi heavy traffic with ambient temps in the 90s most of the year. The construction seems sturdier than the mishimoto it replaces and the higher than stock pressure rating is needed for my application (300whp wrx) and ambient temps. Just make sure to install it in the recirculation tank near the turbo (never on the radiator itself) The oem radiator cap will still be of a slightly higher pressure rating (20psi) vs this cap's 18.5psi (1.3bar) as the system is designed for the recirculation tank to open first when pressure rises over.

Prova Cap is a Winner, will buy again! 4 years agotahuyaguy93948
Installed on my '95 Nissan 300ZX. The Prova 1.3 bar cap is a very handsome cap. The price is right, too. It's hard to find a better deal on a high quality cap with silicon seals. Natural rubber seals on cheaper caps are worthless. Rubber seals quickly harden and stop working. Where rubber seals fail silicon will keep a tight seal helping your cooling system work they way it should.

QUESTIONS & ANSWERS

I understand the aesthetic value enhancement, but are there any adverse effects having increased pressure resistance with a factory radiator (seems like a debatable subject on forums)? Planning to replace both on my '13 Hatch and wanted to verify it was worthwhile (from your more knowledgeable viewpoints) prior to acquisition.

A:
There should be no negative effects from upgrading to 1.3 bar radiator caps with the stock radiator as long as it is in good condition. Increased pressure could cause a minor leak to get worse.
